Figure 6.

Illusion of the current source density ${\mathbf{f}}_{}^{\square }$ by cloaking of the current source density ${\mathbf{f}}_{}^{+}$ (a; see also Fig. 2) using cloaking devices ${\mathbf{f}}_{c,\alpha }^{+}$ (b) and ${\mathbf{f}}_{c,\alpha }^{\square }$ (c). Panel (d) represents a composition data on electric potential, which will be measured in the case of illusion (Eq. 16), and panel (e) illustrates the reconstruction of current source density from these measured data.
